Assessment of carbon stocks
Land-use analysis at the start of the programme
Partnership: IOGA (Institute and Observatory og Geophysics of Antananarivo)
Objective: Treatment and analysis of Very High Definition images provided by Spot Image's initiative Planète-Action to precisely analyze and assess land-use patterns and the different types of forests in the project area (as the highest quantities of carbone are stored in the forests).

Spiny forests are particularly challenging for teledetection, because they often consist of low trees with light foliage, which can be confused with bare soil.
Assessment of the above-ground biomass
The largest amount of forest carbone is stored in the above-ground biomass (stems, branches, leaves). This is why we are putting a lot of efforts on this topic. We have chosen a state-of-the-art methodology for which two complementary stages need to be completed:
Objective: Provide a very precise measurement of the height of the forest canopy and understory in the sites of the project.

Objective: Matching LiDAR data with information gathered through ground surveys and analysis in laboratory to estimate with accuracy the quantity of carbon stored in the above-ground biomass.

Partnerships:
1. IRD (Institut de recherche pour le développement) - Eco and Soils Unit
2. LRI (Laboratoire des Radio-Isotopes) - University of Antananarivo
3. ESSA-Forêts (University of Agricultural Sciences of Madagascar)
Objective: infra-Red Spectrometric measurements on carbon stocks in both litter and soil in Fort-Dauphin and Andapa/Bealanana; and modeling of the evolution of these stocks under the effect of the rise of temperatures.
